Polynomial Functions

A polynomial function is an expression consisting of variables raised to nonnegative integer powers with corresponding coefficients. The shape of its graph is determined by various factors, primarily the highest degree term, which strongly influences the overall behavior of the function.

Degree of a Polynomial

The degree, which is the highest power of the variable in the polynomial, plays a critical role in determining the general shape of the graph and the maximum number of turning points. Higher degree polynomials can have more complex shapes with multiple peaks and valleys.

Leading Coefficient Test

The leading coefficient test helps predict the end behavior of the polynomial's graph. The sign and magnitude of the leading coefficient, in combination with the degree, indicate whether the graph rises or falls as the variable tends towards positive or negative infinity.

End Behavior

The end behavior of a polynomial function describes the trend of its graph as the input values approach extreme positive or negative values. It is directly influenced by the highest degree term, and it determines the general orientation and shape of the graph's tails.
